Hear Berkeley Lab present findings from recent DOE-funded research on land-based and offshore wind energy cost reductions. The DOE-funded 2020 research shows that experts now expect land-based and offshore wind costs to decline ~35–50% by 2050, resulting in costs 50% lower than predicted in 2015. According to the findings, turbine scale is a key driver for cost reduction. Wind turbines are expected to be 2–3 times larger by 2035, with a median of 5.5 MW for land-based turbines and 17 MW for offshore turbines.
